QUANTUM PHYSICISTS CONFIRM SPOOKY INSTANT CORRELATIONS
Researchers in the Netherlands, Spain, and the UK have confirmed in the lab that the weird instant correlations between remote "entangled" particles are real. The experimental result has important implications for both fundamental physics and future cryptography.
The research is published in the arXiv preprint repository with the title "Experimental loophole-free violation of a Bell inequality using entangled electron spins separated by 1.3 km." The paper, freely available online, hasn't been published yet in a peer-reviewed journal, but the result is spreading virally on the Internet.
A summary by Zeeya Merali on the Foundational Questions Institute (FQXi) website is trending on Redditwith thousands of upvotes and comments. Merali has also written an article for Nature News titled "Quantum 'spookiness' passes toughest test yet."
History-Making Confirmation of 'Spooky Action at a Distance'
Quantum physics as it's currently understood doesn't predict the values of a particle's observable properties such as position and spin, but only their probabilities, encoded in the "quantum state" of the particle. It's only after a measurement has been made that the particle snaps randomly into a state with a definite value of the property that has been measured. What constitutes "a measurement," and how ghostly quantum states "collapse," is tentatively answered by the different interpretations of quantum physics that have been proposed.
Quantum entanglement is a phenomenon where two remote particles share a unique quantum state in a way that we are unable to visualize. For example, the shared quantum state may be such that the spins are always measured in opposite direction (1 up and 2 down, or 1 down and 2 up). The researchers measured the spins of hundred of entangled particles in two University of Delft labs, located 1.3 km apart, and confirmed that the entangled correlations are still observed when there is not enough time for light to travel from the first lab to the second, which means that entanglement isn't limited by the speed of light.
Einstein argued against the "spooky action at a distance" between entangled particles, but experimental results seem to side with entanglement.
Instant entanglement has been observed in the lab since Alain Aspect's experiment in the early 80s, but this is the strongest experimental confirmation to date.
“It is a truly ingenious and beautiful experiment,” said renowned University of Vienna quantum physicist Anton Zeilinger. "I wouldn’t be surprised if in the next few years we see one of the authors of this paper, along with some of the older experiments, Aspect's and others, named on a Nobel prize," added Perimeter Institute quantum physicist Matthew Leifer.
Nicolas Gisin, a quantum physicist at the University of Geneva in Switzerland, said: From a fundamental point of view, this is truly history-making.
Gisin is on the Board of Directors of Id Quantique, a company in Geneva specialized in quantum cryptography. The new experimental result confirms the core idea of quantum cryptography: entangled particles can be used to generate secure encryption keys between two remote locations, and malicious agents trying to eavesdrop to intercept the keys would break the entanglement, which could be detected.
"This may enable the realization of large-scale quantum networks that are secured through the very same counter-intuitive concepts that inspired one of the most fundamental scientific debates for 80 years," conclude the researchers.
Many commenters on the Reddit thread speculate that perhaps instant entanglement could be used for instant communications, not limited by the speed of light. But, according to our current understanding of quantum physics, that doesn't seem to be the case. Measuring the spin of one of a pair of entangled particles always gives a random result - even if the results of the two measurements are correlated - and any attempt to preset the spin of a particle would break the entanglement. A good analogy is two decks of "magic" cards that are always in the same order, but the magic only works if both decks are well shuffled first, and cheating breaks the magic.

/ About us
Founded by Russian entrepreneur Dmitry Itskov in February 2011 with the participation of leading Russian specialists in the field of neural interfaces, robotics, artificial organs and systems.
The main goals of the 2045 Initiative: the creation and realization of a new strategy for the development of humanity which meets global civilization challenges; the creation of optimale conditions promoting the spiritual enlightenment of humanity; and the realization of a new futuristic reality based on 5 principles: high spirituality, high culture, high ethics, high science and high technologies.
The main science mega-project of the 2045 Initiative aims to create technologies enabling the transfer of a individual’s personality to a more advanced non-biological carrier, and extending life, including to the point of immortality. We devote particular attention to enabling the fullest possible dialogue between the world’s major spiritual traditions, science and society.
A large-scale transformation of humanity, comparable to some of the major spiritual and sci-tech revolutions in history, will require a new strategy. We believe this to be necessary to overcome existing crises, which threaten our planetary habitat and the continued existence of humanity as a species. With the 2045 Initiative, we hope to realize a new strategy for humanity's development, and in so doing, create a more productive, fulfilling, and satisfying future.
The "2045" team is working towards creating an international research center where leading scientists will be engaged in research and development in the fields of anthropomorphic robotics, living systems modeling and brain and consciousness modeling with the goal of transferring one’s individual consciousness to an artificial carrier and achieving cybernetic immortality.
An annual congress "The Global Future 2045" is organized by the Initiative to give platform for discussing mankind's evolutionary strategy based on technologies of cybernetic immortality as well as the possible impact of such technologies on global society, politics and economies of the future.
Future prospects of "2045" Initiative for society
2015-2020
The emergence and widespread use of affordable android "avatars" controlled by a "brain-computer" interface. Coupled with related technologies “avatars’ will give people a number of new features: ability to work in dangerous environments, perform rescue operations, travel in extreme situations etc.
Avatar components will be used in medicine for the rehabilitation of fully or partially disabled patients giving them prosthetic limbs or recover lost senses.
2020-2025
Creation of an autonomous life-support system for the human brain linked to a robot, ‘avatar’, will save people whose body is completely worn out or irreversibly damaged. Any patient with an intact brain will be able to return to a fully functioning bodily life. Such technologies will greatly enlarge the possibility of hybrid bio-electronic devices, thus creating a new IT revolution and will make all kinds of superimpositions of electronic and biological systems possible.
2030-2035
Creation of a computer model of the brain and human consciousness with the subsequent development of means to transfer individual consciousness onto an artificial carrier. This development will profoundly change the world, it will not only give everyone the possibility of cybernetic immortality but will also create a friendly artificial intelligence, expand human capabilities and provide opportunities for ordinary people to restore or modify their own brain multiple times. The final result at this stage can be a real revolution in the understanding of human nature that will completely change the human and technical prospects for humanity.
2045
This is the time when substance-independent minds will receive new bodies with capacities far exceeding those of ordinary humans. A new era for humanity will arrive! Changes will occur in all spheres of human activity – energy generation, transportation, politics, medicine, psychology, sciences, and so on.
Today it is hard to imagine a future when bodies consisting of nanorobots will become affordable and capable of taking any form. It is also hard to imagine body holograms featuring controlled matter. One thing is clear however: humanity, for the first time in its history, will make a fully managed evolutionary transition and eventually become a new species. Moreover, prerequisites for a large-scale expansion into outer space will be created as well.
